KUBUNTU/UBUNTU Display only working at 640x480 3dFX Voodoo3 bios 1.2

All,

Whenever I install KUBUNTU or UBUNTU on my Gateway Performance PIII with a 3dFx Voodoo3 video card with bios version 1.2, I am not able to change the display resolution.  The only choices are 640x480 and 320x240 and the refresh is set at 60Hz.  If I install Fedora or SUSE, I do not experience this problem.  Can anyone tell me how to get and load the drivers for the 3dFx Voodoo3 AGP card?

Thanks.
